Answer:
8 days
Step-by-step explanation:
Since A and B can do together a pice of work in 8 days
Since B and C can do together a pice of work in 12 days
Since A,B and C together can complete a pice of work in 6 days
∴ A+B = 8 days .............. (1)
B+C = 12 days ..............(2)
A+B+C =6 days ...........(3)
Putting (2) in (3) , to get A;
∴ A can complete the work in 6 days.
Putting (1) in (3) , to get c;
∴ C can complete the work in 2 days
